This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Linkhut account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Linkhut with - [OpenAI Agents SDK](https://composio.dev/toolkits/linkhut/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/linkhut/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/linkhut/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/linkhut/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/linkhut/framework/codex) - [OpenClaw](https://composio.dev/toolkits/linkhut/framework/openclaw) - [Hermes](https://composio.dev/toolkits/linkhut/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/linkhut/framework/google-adk) - [LangChain](https://composio.dev/toolkits/linkhut/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/linkhut/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/linkhut/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/linkhut/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/linkhut/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/linkhut/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/linkhut/framework/autogen) ## TL;DR ### How Atomic Agent connects to Linkhut Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Linkhut to Atomic Agent ### Connect Linkhut to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Linkhut. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Linkhut account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Linkhut MCP server, and what's possible with it? The Linkhut MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Linkhut account. It provides structured and secure access to all your saved bookmarks, so your agent can organize, tag, retrieve, and manage your URLs and references exactly how you want. - Bookmark organization and retrieval: Effortlessly ask your agent to fetch, list, or filter all bookmarks, including details like tags, notes, and timestamps. - Automated link saving: Let your agent add new bookmarks for important websites, articles, or resources—tagged and noted for easy discovery later. - Tag management and insights: Have your agent pull a list of all used tags, track how often tags appear, and help you keep your bookmark library organized. - Bookmark editing and updates: Direct your agent to modify titles, descriptions, or tags for any saved link so your collection always stays current and relevant. - Bookmark cleanup and removal: Ask your agent to delete obsolete or unwanted bookmarks, keeping your Linkhut workspace clean and focused. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `LINKHUT_ADD_BOOKMARK` | Add bookmark | Adds a new bookmark to LinkHut. The bookmark can be marked as private/public and read/unread, with optional tags and notes. | | `LINKHUT_DELETE_BOOKMARK` | Delete bookmark | This tool allows users to delete a bookmark from their Linkhut account by providing the bookmark URL. It operates independently and only requires the URL parameter to identify and remove the bookmark. | | `LINKHUT_GET_ALL_TAGS` | Get all tags | Retrieves a list of all tags and their usage counts for the authenticated user. No additional parameters required besides authentication. | | `LINKHUT_GET_BOOKMARKS` | Get bookmarks | Retrieves bookmarks from the user's Linkhut account with optional filtering. This tool fetches bookmarks from Linkhut and supports filtering by: - Tag: Filter by one or more tags (space-separated) - Date: Filter by a specific date (ISO8601 format) - URL: Get a specific bookmark by its exact URL - Meta: Request additional metadata about bookmarks Returns a list of bookmarks with details including URL, title/description, tags, extended notes, timestamp, privacy status (shared), and read status (toread). | | `LINKHUT_UPDATE_BOOKMARK` | Update Bookmark | This tool allows users to update an existing bookmark in LinkHut. The tool updates the metadata of a bookmark including its title, description, and tags. | ## Supported Triggers None listed. ## Troubleshooting ### Why is my API key rejected? Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Linkhut from Atomic Agent With your account connected, ask Atomic Agent to work with Linkhut in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Linkhut MCP server, the agents and LLMs can only access a fixed set of Linkhut tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Linkhut and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Linkhut tools. ### Can I manage the permissions and scopes for Linkhut while using Tool Router? Yes, absolutely. You can configure which Linkhut scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Linkhut data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
